To all whom it may concern:

Be'it known that 1, JOHN BAER, a subject of the Emperor ofGermany,residing at Philadelphia, Pennsylvania, have invented certainImprovements in Machines for Beatingthereon; and this object I attain inthe manner hereinafter set forth,reference being had to the accompanyingdrawings, in which- Figure 1 is a longitudinal section, partly inelevation, of a machine constructed in accordance with my invention.Fig. 2 is ,a plan of the same with part of the machine removed to moreclearly illustrate the parts beneath. Fig. 3 is an elevation and atransverse section of the machine on the line 1 2, Fig. 1.- Fig. 4 is anelevation and a transverse section on the line 3 4., Fig. 1; and Fig. 5is a View illustrating a modification of part of the invention. I a

It may be stated at the outset that the machine has been devised mainlyfor treating cut pile fabrics-such as plushesafter they are dyed andbefore drying, the object being to raise the nap or pile by combing andbeating the fabric while it is in a wet or damp condition, theseoperations being now generally performed by hand.

A represents the frame-Work of the machine to suitable bearings in whichis adapted a driving-shaft a, having fast and loose pulleys a a for thereception of a driving-belt, this shaft being geared by spur-wheels a ato a transverse shaft B,'which is geared by bevel-wheels b b tocounter-shafts D-one at each side of the machine.

At one end of the machine is a delivery roll E, covered withcard-clothing or having its surface otherwise toothed or roughened, andat the other end of the frame is a draftroll E, having a similarsurface, so that the strip a: of plush or other out pile fabric will bedrawn forward through the machine, suitable rolls dserving to supportand guide the fabric in its passage. The shafts of the rolls E E havepulleys e, which are driven by belts e from pulleys on the transverseshaft B, the proportions'of these pulleys being such that the roll Ewill have a slightly greater surface speed than the roll E, so as tomaintain the fabric constantly under tension during its passage throughthe machine. The fabric in its passage is subjected first to atransverse or crosswise combing, then to the action of vibratingheaters, and finally to a longitudinal or lengthwise combing. Forperforming the first of these operations-that is, the combing of thepile of the fabric cross-. wise of the stripa transverse frame A islocated adjacent to the delivery-roll E, and this frame has bearings foropposite shafts f, carrying sprocket-wheels f these sprocketwheels ordrums being connected by chain belts f on which are cross-bars g, andprojecting' from the latter are elastic stems or shanks g carrying attheir outer ends the on the surface and covered with card-clothing orlike toothed material. The shaft f at one end of the frame A has apulley c, driven by a belt 0 from a pulley c on one of thecounter-shafts D of the machine, so that the combs F are drawn insuccession across the face of the fabric, the pile of which is thussubjected to a combing action in a direction transversely to the lengthof the strip of fabric, shanks g of the combs causing the latter to actupon the fabric in substantially the same manner as the hand-combs nowused for that purpose. At one side of the frame A is an inclined table'or bench h, having a toothed surface h, over which the combs F are drawnbefore they act upon the fabric, thus removing from said combs anystrands or'fibers that may be caught in the same, and thus maintainingthe combs in proper acting condition. The beating of the fabric after ithas been subjected to the transverse or crosswise combing action justdescribed is effected by bars G, which are hung upon shafts Gat'opposite sides of the machine and have projecting toes i, acted uponby cams H, secured to the opposite counter-shafts D, the cams serving tolift the bars, and springs 01 serving to depress the same and bring theminto contact with the fabric after the toes -i are released from theaction of the cams, which are preferably so arranged upon the shaftsthat the barsact successively from one end of the set combs F, thelatterbeing preferably convex the yielding or elastic to the other. Eachbar has a rearwardlyprojecting heel 2' and above the outer ends of theseheels is mounted an adjustable stop, by which the rise of the heel, andconsequently the descent of the beating-bar, may be restricted and theforce of the blow delivered by the beater thereby regulated, it beingunderstood that each of the beater-barshas a certain amount ofelasticity, so that it will strike the fabric even although the movementof the bar permitted by the stop would not be sufiicient to bring thebar into contact with the fabric if said bar were rigid. The stops inthe present instance are cams I, each consisting of a bar mountedeccentrically in suitable bearings on the frame A, the shaft of each barbeing provided at one end with an arm k, the arms of the opposite shaftsbeing connected by a rod and one arm being provided with a handle 70 sothat by manipulating this handle the opposite bars I may besimultaneously adjusted so as to regulate the movement of thebeater-bars, or so as to lift them free from the fabric altogether whenit is desired to intermit the action of the beater-bars upon the fabric.If it is not considered necessary to operate or regulate the beater-barsindependently, they may be secured to the shafts G, in which case butone of the bars of each shaft need have a toe to be acted on by alifting-cam and a heel for contact with the stop.

Beyond the heaters the frame A of the machine has bearings for theshafts of drums J, which have sprocketteeth engaging with chain belts m,the latter having cross-bars 91, carrying the spring-shanks n of combsK, similar to the combs F, and serving to comb the pile of the fabric inthe direction of the length of the strip, the shaft of one of the drumsJ being driven from the transverse shaft B through the medium of pulleysp p and belt 112, so that the combs K travel over the surface of thefabric in a direction contrary to the direction of movement of thefabric itself. Above the drums J is an inclined table or plate L,toothed on the under surface and occupying such relation to the belts mand the combs K, carried thereby, that said combs will be drawn alongthe toothed surface of the plate, and will be cleaned thereby in thesame manner as the combs F are cleaned by the toothed surface of theplate h. It will be observed on reference to Fig. 2 that the width ofeach comb K is but a fraction of the entire width of the fabric, so thatthe successively-acting combs act upon different and preferably uponadjacent lateral portions of the strip of fabric, this being found to bethe most effective method of operation, and one which, moreover, reducesthe power necessary to drive the machine as compared with what would berequired if combs of the full width of the strip of fabric wereemployed.

In order to insure a comparatively long travel of each comb over theface of the fabric passing beneath the same, and yet pre- -coiledsprings.

vent that strain or pressure upon the comb which would be caused if thespring-shanks n were carried around the rear drum J while the comb wasstill in contact with the fabric, I place between the drums J J ahearing or directing roller M, which serves to cause the belts m to takea substantially horizontal course for a considerable distance afterleaving the forward drum J, and yet permits the upward deflection of therear portions of the belts, so that the ends of the shanks graduallyrise on a gentle incline and each comb K is free from contact with theface of the fabric before the shanks carrying said comb reach the reardrum J.

Although it is preferable in carrying out my invention to use traversingbelts as a means of carrying the combs, this is not absolutely essentialto my invention. For instance, in Fig. 5 Ihave shown a modified form ofthe device in which the flexible shanks or stems s of the combs aresecured to arms 5', projecting from a shaft P, the flexible shanks inthis case being represented as formed by The arms in this case are soarranged upon the shaft as to cause the successive action of the combsof the series in the same manner as when the combs are mounted uponbelts, as originally described.

The machine constructed in the manner set forth is adapted for actingupon other classes of cut pile fabrics besides plushes and velvets,although, as before stated, it has been designed especially for treatingthe latter class of goods and intended to supplant the hand treatmentnow considered necessary.

It should be understood that my invention is entirely distinct from thatclass of machines in which a strip of fabric is traversed in contactwith the toothed surface of a rotating drum, it being essential tothe'proper carrying out of my invention that the toothed combs should bedrawn along the surface of the fabric for a considerable distance whilein position to exercise a combing efiect upon the pile of the fabric.

Having thus described my invention, I claim and desire to securebyLetters Patent?- 1. The combination of mechanism for supporting andtraversing the strip of fabric with two sets of combs, mechanism fortraversing one set of combs crosswise of the fabric and the other setlengthwise of the same, a set of heaters, and means for operating thesame, said set of beaters being located between the two sets of combs,whereby the final action upon the fabric is that of one of the sets ofcombs, substantially as specified.

2. The combination of means for supporting and traversing the strip offabric with a belt or equivalent carrier, means for operating the same,and a toothed comb supported on said carrier by means of a spring stemor shank, substantially as specified.

3. The combination of means for supporting and traversing the fabric, abelt or equivalent carrier, means for operating the same, and combssupported on said carrier by means of spring stems or shanks, said combshaving toothed convex faces for acting on the fabric,-substantially asspecified.

4. The combination of means for supporting and traversing the fabric, abelt or equivalent comb-carrier, means for operating the same, combshaving spring stems or shanks connected to said carrier, and a toothedplate or table with which the combs are brought into contact in theirpassage, substantially as specified.
